Patent DE-3718406-A1 (DE)
Title: Method for braking rolled bars and an approach roller table for cooling beds for carrying out the method
Inventor: MUELLER HUBERT
IPC: B21B43/00
Filed: 1987-06-02
Abstract: A description is given of a method for braking moving rolled bars of differing lengths in the region of the approach roller table of cooling beds, in which method the braking force is provided by friction between the respective surface of the rolled bar and static and/or dynamic braking surfaces, e.g. those of braking slides and braking drivers, acting on it. Minimum length dimensions are achieved for a cooling-bed installation because the braking force on the rolled bars up to a predetermined limiting length is provided exclusively by static braking surfaces. Rolled bars with a length that exceeds this limiting length, on the other hand, are additionally subjected to the action of dynamic braking surfaces. The duration and/or intensity of action of the dynamic braking surfaces is/are determined by the difference between a likewise predetermined maximum length of rolled bar and the particular effective length of rolled bar.

Title: Circuit arrangement for limiting current when inserting a subassembly (module)
Inventor: DREIER BENNO DIPL ING
IPC: H02H9/00
Filed: 1988-04-22
Abstract: A circuit arrangement is given for limiting the current surge which is caused, when a subassembly is inserted into a device which is in use, by the action of uncharged capacitors (CL) of the subassembly and can lead to (voltage) dips in the device. According to the invention, an n-channel MOSFET of the enhancement type (FT) is provided in the main current path of the subassembly, the control junction of which transistor is subjected to a slowly increasing control voltage. The effect of the control voltage is that the switching junction of the MOSFET is brought from the non-conducting state into the low-resistance conducting state according to a predetermined time function. The control voltage, which must be higher than the voltage (+UB) to be switched, is generated using an AC generator (T1, RG, CG) and a rectifier circuit (GS), having voltage doubler or voltage multiplier function, which is connected downstream. <IMAGE>

Patent DE-3823387-A1 (DE)
Inventor: KONRAD ANDREAS DIPL ING
IPC: B60W30/18
Filed: 1988-07-09
Abstract: For the control of an automatically actuated friction clutch of a motor vehicle driven by an internal combustion engine (1), in manoeuvring operation, that is at creeping speed, it is provided that the power output setting device (15) of the internal combustion engine (1) permits a limited preliminary accelerator pedal travel (13) which does not influence the power output of the internal combustion engine. The automatically actuated friction clutch (3) is engaged and disengaged by a control system (9) which responds at accelerator pedal positions within the preliminary pedal travel to a sensor (17) detecting the pedal position and in dependence upon the sensor sets the clutch (3) to an intermediate value between the completely engaged and the completely disengaged positions, at which the clutch (3) already transmits a partial torque sufficing for manoeuvring. In this action the internal combustion engine (1) is working with its idling rotation rate or a slightly increased rotation rate. The power output setting device of the internal combustion engine preferably has an idling rotation rate regulating device in order to be able, even in manoeuvring, to compensate for variations in the power output requirement, for example by reason of a gradient or a kerbstone edge. In a second embodiment the accelerator pedal operates change-over switches to alter input connections to a comparator, one of the connections being to an engine speed sensor. <IMAGE>

Patent DE-3831393-A1 (DE)
Title: Support plate
Inventor: GREBE WOLFGANG PROF DR ING
IPC: B26F1/44
Filed: 1988-09-15
Abstract: Support plates form the means of holding the cutting and grooving (scoring) lines in strip(hoop)-steel stamping tools. The strip-steel tools operate against a stamping plate which contains grooved slots into which the grooving lines press the material to be shaped. Maximum dimensional accuracy is therefore important. The support plates have hitherto been made of wood. In changing humidity these are dimensionally instable which leads to inaccuracies when cutting and to the groove-makers being displaced relative to the grooved slots and thus to breakdowns in production. In order to solve the instability caused by humidity, a plate construction is proposed which is made of materials which do not, or in interaction with other materials virtually do not react to changes in humidity, in the form of a fibre structure, for example as glass-fabric inserts in conjunction with plastics as volume-enhancing filler, which can be cut by sawing, milling, water jet or laser beam.   The plate is preferably conceived for use as a supporting plate for strip-steel stamping and grooving tools.

Title: Method for measuring the total distance between a transmitting location, a reference location and a receiving location
Inventor: LANDSTORFER FRIEDRICH PROF DR
IPC: G01S13/75
Filed: 1988-11-30
Abstract: The method enables highly accurate non-touching distance measurement between the transmitting location, a reference location and the receiving location. In this case, the frequency of the modulated carrier-frequency signal transmitted by the transmitter is converted in a transponder at the reference location, so that said signal can easily be differentiated from random echoes at the receiving location. The distance measurement is carried out by comparing a reference signal derived from the transmitter with the demodulated received signal. The method in this case uses an extremely simple transponder which manages entirely without any electrical power being supplied from the outside. In the simplest case, the transponder consists of a semiconductor diode and a transmitting and receiving antenna.

Abstract: In order to achieve optimum applicational properties of aqueous surfactant solutions, thickeners are added to these solutions. The known thickeners must be added to the surfactant systems in high concentrations which may be, for example in the case of electrolyte thickeners, so high that skin irritations may occur. The novel thickener mixtures do not have these disadvantages. Thickeners for surfactants and surfactant systems are proposed which comprise a mixture of a nonionic surfactant having an HLB value of from 4 to 11 with a polymer. The nonionic surfactant used is a compound of the general formula R-(BO)e(CH2CH2O)f-X and the polymer used is a compound of the general formula x[R<1>-(CH2CH2O)b (BOa]-A-[(BO)c (CH2CH2O)d-R<2>]y. These mixtures do not have the abovementioned disadvantages. A synergistic thickening effect occurs. These thickener mixtures are used in concentrations of only from 0.05 to 10% in surfactants and surfactant systems.
